Abstract
Provided is a radio wave absorber for a high-frequency communication apparatus that can improve mass productivity, reduce costs, and further achieve weight reduction. For this purpose, a radio wave absorber includes a side part surrounding a semiconductor element fixed to a base part provided in a high-frequency communication apparatus and a top part closing an open face surrounded by the side part. An inner face of the top part is provided with a plurality of protruding parts protruding toward the semiconductor element positioned inside the radio wave absorber, positioned spaced apart from the semiconductor element, and periodically arranged. The protruding parts are formed to be tapered toward the semiconductor element and are integrally molded of a synthetic resin.
